Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you're looking for some sturdy but still growing giants to add to your portfolio, the Vanguard Mega Cap 300 Growth Index ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The Vanguard ETF's expense ratio -- its annual fee -- is a very low 0.12%.
This ETF has performed reasonably well, beating the S&P 500 over the past three years and also so far this year. As with most investments, of course, we can't expect outstanding performances in every quarter or year. Investors with conviction need to wait for their holdings to deliver.
With a low turnover rate of 26%, this fund isn't frantically and frequently rejiggering its holdings, as many funds do.
What's in it?
Plenty of huge and growing companies had strong performances over the past year. Philip Morris International
Data storage titan EMC
The big picture
A well-chosen ETF can grant you instant diversification across any industry or group of companies -- and make investing in and profiting from it that much easier.
